Abstract
ABSTRACT OF THE INVENTION:
The invention features a strain relief device for mounting wires and cable into a panel. The body of the device carrying the cable is flexible and attached to the panel by a rotational motion. The panel is locked between two flange sections of the body by a number of locking ramps that bias one of the flanges into locking engagement with the panel.

SLEEVE FOR CABLES
FIELD OF THE INVENTION:
The invention features a strain relief device for installation of wire S and cable into panelling, and more particularly to a flexible strain relief device that is easily mountable in a panel and which can accommodate a variety of wire and cable.
BACKGROUND OF THE I~VENTION:
In mounting power supply cords and other electrical wires or cables in a panel, it is necessary to install them, such that strain is not imposed upon the copper conductors and the surrounding insulation. The stressing of wires or cables at their points of contact with panelling can lead to serious shorting or disruption of the electrical current.
In the past, a strain relief device was utilized to alleviate cable stresses, wherein the device housing was clamped around the cable and threaded into the panelling. While the threaded strain relief protected the wires, it wastoo cumbersome and costly to install.
The present invention features a new strain relief design that quickly and easily mounts to a panel, and which has the further advantage of ; 20 accommodating wires, cords and cables of varying types, materials, and construction. The strain relief device of this invention will provide good retention of the wires subject to both no~mal and torsional forces applied at the entry point in the panel.

BRlEF SUMMARY OF THE rNVENTION:
The invention relates to a flexible strain relief device for installing wire or cable into a square aperture disposed in panelling. The device comprisesa flexible body having a wire or cab}e supporting conduit. The entrance of the conduit is disposed at a rear portion. First and second flange sections are provided at the rear portion of the body. These flange sections are approximately square in shape. The flange sections are spaced apart by at least a thickness of the panelling, and have an approximate 45 degree orientation withrespect to each other, i.e. the flange sections are displaced at an angle of 45 degrees about a central body axis.
The strain relief device is inserted in the square aperture of the panelling by orienting the body at approx~nately 45 degrees with respect to an upright position, i.o. at a 45 degree ang1e about the central body axis. In thisposition, the first flange section will pass through the square aperture. The strain relief device is then rotated approximately 45 degrees back to the upright position, wherein the first flange section becomes locked behind the panelling.
The panelling is now disposed between the first and second flange sections.
The first flange section has chamfered corners that allow the flange section to pass through the square aperture in the panelling at a 45 degree orientation, but become locked in the upright position.
A number of ramps disposed along a front poqtion of the first flange section biase`s the strain relief device into locking engagement with thepanelling. Each ramp is disposed about a co~ner of the lSrst flange section.

The front portion of the first flange section is disposed oppositely a rear portion of the second flange section, so that the panelling will become locked between the two flange sections.
A pair of holes in the body receive the teeth of a torquing tool for S rotating the body of the strain relief device with respect to the panelling.
It is an object of the invention to provide an improved strain relief device.
It is another object of this invention to provide a strain relief device that is easy to install and can accommodate many different wire, cord, and cable types.
These and other objects of the invention will become more apparent and will be better understood with respect to the following detailed description considered in conjunction wi~h the accompanying drawings.

DETAILED DPSCRIPIION OF T~ IN~NTION:
Generally speahng, the invention pertains to a strain relhf device for mounting wires or cables to a panel ~or the sake of brevity, like elements will be assigned the same designation tbroughout the drawings Referring now to the figures, and particularly to Pigure 1, a strain ~; relief device 10 of this invention is illustrated in an upright position with respect to a square aperture 11 in a panel 12 into which it is to be inserted (arrow 13).
The strain relief device 10 is made of a flexible material such as hard rubber, and cames a cable 14 in a conduit 15 (Figure 8) run~ung through : its one-piece body 16, from a bottom entrance 17 to a rear exit 18.
The body 16 of device 10 has a snubbed-nose section 19 for protecting the cable 14 from shock forces ~:

~ , , . ~ ... .; : .
~X~169~3 The rear portion 20 of body 16 has two flanges 21 and 22, respectively. The flanges 21 and æ are separated by a groove 23 having a thickness "d" equal or slightly greater than the thickness "D" of plate 12, as best seen in Figures 8 and 9. Figures 8 and 9 illustrate the device 10 mounted to S plate 12.
Flange 21 and 22 are approximately square-shaped, except that the corners "A" of flange 21 are chamfered to give an octagonal appearance, as best seen in Figures 3 and 10.
When the device 10 is to be inserted into (arrow 13) aperture 11 of plate 12 (Figure 1), it is necessary to rotate (arrow 24) the body 16 from its illustrated upright position, and push (arrow 13) flange 21 into aperture 11.
At an angle of 45 degrees counterclockwise about center axis 30, the chamfered corners A of flange 21 will clear the corner sections "B" of aperture 11, and allow the flange 21 to pass behind plate 12.
If the body 16 is now rotated back to its upright position (45 degrees clockwise), the corners A of flange 21 will lock into place behind plate: 12, thus attaching the strain relief device 10 to piate 12. 1~ this locked position, the plate 12 is disposed in groove 23 between the flanges 21 and æ, respectively.
A locking fft is insured by means of ramps 27 cut into co~ners A
of flange 21, which provided camming leverage between the plate 12 and flange 21, when the body 16 is rotated 45 degrees clockwise to the upright position shown in Figure 1.

1~1698 Holes 32 may be provided in body 16 for receipt of a torquing tool (not shown) for rotating the body 16 about axis 30 in a clockwise direction.
A typical cable 14 that can be used with device 10 can be a power cord having three insulated conductors 33, as depicted in Figures 3, 7 and 10.
C)f course, the device 10 can also be utilized with other types of wire or cabling, as befits the need. Flat and square cordage can also be used with the inventive strain relief device. Appropriate modifications will occur to those skilled in this art.
